Argon isotopic analysis of breccia veins from the Roter Kamm crater, Namibia, and implications for their thermal history

Autor: Arch M. Reid, Peter Copeland, David Rajmon

Publikováno v: Meteoritics & Planetary Science. 40:841-854

The rocks exposed in the rim of the 2.5-km-wide and 3.7-Ma-old Roter Kamm crater in southwest Namibia are cut by breccia veins that macroscopically resemble, and were originally described as, pseudotachylytes. The veins were later shown to be catacla

Reconstruction Of The Subsurface Structure Of The Marquez Impact Crater In Leon County, Texas, Usa, Based On Well-Log And Gravity Data

Autor: Virgil L. Sharpton, Alan M. Wong, Arch M. Reid, Stuart A. Hall

Publikováno v: Meteoritics & Planetary Science. 36:1443-1455

— In Leon County, Texas, USA, the Marquez Dome, an approximately circular 1.2 km diameter zone of disturbed Cretaceous rocks surrounded by shallow dipping Tertiary sediments, has been interpreted by Gibson and Sharpton (1989) and Sharpton and Gibso

Syndepositional shallow-water precipitation of glauconitic minerals

Autor: Henry S. Chafetz, Arch M. Reid

Publikováno v: Sedimentary Geology. 136:29-42

Numerous studies have demonstrated that glauconitic minerals predominantly form in water depths of mid-shelf to upper slope in modern oceans. These areas tend to have slow sedimentation rates, another commonly cited requisite for glauconitic mineral

Impact into unconsolidated, water-rich sediments at the Marquez Dome, Texas

Autor: Paul C. Buchanan, Christian Koeberl, Arch M. Reid

Publikováno v: Meteoritics & Planetary Science. 33:1053-1064

— The Marquez Dome, Leon County, Texas represents a 13 km diameter Paleocene/Eocene impact structure formed in largely unconsolidated sediments in a near-shore environment. The present study is an analysis of samples from cores taken from boreholes

Mn- and Fe-rich black travertine shrubs; bacterially (and nanobacterially) induced precipitates

Autor: Ramon Julià, Arch M. Reid, Henry S. Chafetz, Brahim Akdim

Publikováno v: Journal of Sedimentary Research. 68:404-412

Black shrubs (i.e., arborescent forms) are present within hot-water travertine deposits from Morocco. The shrubs are commonly a few centimeters high and laterally grouped along individual laminae. Other than in mineral composition, the black shrubs c

Parental magma compositions inferred from the chemical compositions of olivine-controlled derivative melts

Autor: Arch M. Reid, John H. Jones, Alex Woronow

Publikováno v: Geochimica et Cosmochimica Acta. 60:577-586

The melt portion of a parental magma, undergoing equilibrium olivine crystallization, passes through a succession of compositions unique to its initial composition. Because the succession of compositions follows uniquely from the parental magma's com

Petrology of the polymict eucrite Petersburg

Autor: P. C. Buchanan, Arch M. Reid

Publikováno v: Geochimica et Cosmochimica Acta. 60:135-146

The polymict eucrite Petersburg contains eucritic and diogenitic materials which span a broad range of compositions. The present study focuses on four eucritic clasts for which bulk compositions and mineralogical data were acquired; the broad composi

Recovery of three ordinary chondrites, Rooikop 001-003, from the Namib Desert in Western Namibia

Autor: Michael E. Zolensky, Arch M. Reid, R. McG. Miller, P. Jakes

Publikováno v: Meteoritics. 30:781-784

— Reconnaissance searches for meteorites were made in five selected areas of western Namibia in 1991. Three new ordinary chondrites (H5, L5, L4/5) were recovered from one of the areas searched.

Carbonaceous chondrite clasts in the howardites Bholghati and EET87513

Autor: Arch M. Reid, P. C. Buchanan, Michael E. Zolensky

Publikováno v: Meteoritics. 28:659-669

Twenty-two carbonaceous chondrite clasts from the two howardites Bholghati and EET87513 were analyzed. Clast N from EET87513 is a fragment classified as CM2 material on the basis of texture, bulk composition, mineralogy, and bulk O isotopic compositi
